WILLIAM H. PRUYN, JR.., OF CHICAGO, ILLINOIS.

CONCRETE RAILWAY-TIE.

To all whom "it may concern:

Be it known that I, WVILLIAM H. PRUYN, Jr., a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement in ConcreteRailway-Ties, of which the following is a specification.

My invention relates to concrete railway ties and has for its object toprovide certain new and useful improvements more fully set forthhereinafter.

It is illustrated in the accompanying drawings, wherein Figure l is across section through a rail showing a portion of one tie inlongitudinal section, the parts shown in dotted lines; Fig. 2 is adetail cross section on the line 2-2 of Fig. 1; Fig. 3 is a detailperspective of the tie end; Fig. i is a similar View of a modification.

Like parts are indicated by the same letter in all the figures.

A is the rail, B the body of the tie, preferably having the reinforcingrods B B embedded therein.

U is a plate preferably of wood and of any desired thickness, resting ontop of the tie and furnishing a bearing place for the rail.

D, D are securing plates adapted to overhang the flange of the rail.

E E are bolts having bolt heads E E which lie upon the securing plates.These heads are preferably square so that the bolt can be turned bymeans of a wrench, though, of course, they could take any shape andcould be let into the top of the securing plate. The bolt head itselfcould be shaped so as to overhang the flange, thus dispensing with suchsecuring plates. The plate 0 could also be dispensed with though it isthe preferred form.

F F are apertures in the tie for the bolts E E. They terminate below ina transverse pocket G which is preferably about the size of the nut Jinto which the lower end of the bolt is to be secured. This pocket maybe provided with a downwardly projecting aperture J or an enlargementthereof J which latter extends through the base of the tie.

K is a sheet metal lining for the aperture.

The size and proportions of the several parts are capable of greatchange and variation without departing from the spirit of Specificationof Letters Patent.

my invention. I prefer, however, a bolt with a head adapted to begrasped by a proper tool whereby the bolt may be rotated, a bolt holejust about the size of the head, a pocket below just about the size ofthe nut, and a narrow opening below the pocket to receive that end ofthe bolt which projects beyond the nut. To this I would add the plate orshim as it is called which rests upon the top of the tie and receivesthe bottom of the rail. I have shown a sheet metal lining in some of thefigures. It, of course, might be dispensed with but is preferred.

In Fig. 1 I have shown two forms of the bolt, one with the plate D, andthe other with the head E enlarged and shaped so as to overhang theflange of the rail. E is a spike which may be driven down past onecorner of this enlarged head to prevent the bolt from unscrewing.

The use and operation of my invention are as follows: The ties being putin position, the rails upon them, my invention is easily applied for thepurpose of securing the rail in position. The bolt with its railoverhanging part is inserted from above and passed through the hole inthe nut. The nut is slid into place along the ledges at the sides of thepocket. The bolt can then be rotated until the parts are brought tightlytogether, when it will be locked by any suitable locking device and theend of the bolt will project through the pocket into the slot below. Ifdesired this slit can be extended as indicated in Fig. 4 to the bottomof the tie. This is not in every case necessary but furnishes convenientmeans to get at the parts. Then the pocket is of the size indicated, itholds the nut so as to prevent it from rotating and the tieis weakenedby the least possible degree by the several apertures formed in it.

The sheet metal lining when used can be of one piece, thus accuratelydefining the shape of the holes and their several parts and it can beset into the mold, the concrete being filled in about it. With orwithout it, the desired result is the formation of an aperture in whichthe nut will snugly fit so that no tools are required to hold it ormanipulate it but it is brought into position and held there by theshape of the cavity.

I claim:

1. A concrete tie having a vertical bolt hole and an intersecting thinlateral rectangular nut pocket through the exterior wall of the tie, andof such size as to prevent rotation of the nut.

2. A concrete tie having a vertical bolt hole and an intersecting thinlateral rectangular nut pocket through the exterior wall of the tie, andof such size as to prevent rotation of the nut, in combination with abolt which holds the flange of the rail, and a nut supported in thepocket which receives the end of the bolt.

3. A concrete tie having a vertical bolt hole and an intersecting thinlateral nut pocket through the exterior wall of the tie in combinationwith a bolt which holds the flange of the rail, and a nut. in the pocketwhich receives the end of the bolt, said nut pocket of approximately thesame cross section as the nut.

at. A concrete tie having a vertical bolt hole and an intersecting thinlateral nut pocket through the exterior wall of the tie in combinationwith a bolt which holds the flange of the rail, and a nut in the pocketwhich receives the end of the bolt, the side of said nut bearing againstone wall of the pocket when the nut is in position.

5. A concrete tie having a vertical bolt hole and an intersecting thinlateral nut pocket through the exterior wall of the tie in combinationwith a bolt which holds the flange oi the rail, and a nut in the pocketwhich receives the end of the bolt, said nut pocket of approximately thesame cross section as the nut, the inner edge of the nut bearing againstthe inner surface of the pocket.

6. A concrete tie having a vertical bolt hole and an intersecting thinlateral rectangular nut pocket through the exterior wall of the tie, andof such size as to prevent rotation of the nut, and a contracteddownwardly extending opening of smaller area than and below the bottomof the pocket.

7. A concrete tie having a vertical bolt hole and an intersecting thinlateral rec tangular nut pocket through the exterior wall of the tie,and of such size as to prevent rotation of the nut, in combination witha bolt which holds the flange of the rail, a nut in the pocket whichreceives the end of the bolt, and a downwardly extending opening ofsmaller area than and below the bottom of the pocket.

8. A concrete tie having a vertical bolt hole and an intersecting thinlateral nut pocket through the exterior wall of the tie in combinationwith a bolt which holds the flange of the rail, a nut in the pocketwhich receives the end of the bolt, said nut pocket or" approximatelythe same cross section as the nut, and a downwardly extending opening ofsmaller area than and below the bottom of the pocket.

9'. A concrete tie having a vertical bolthole and an intersecting thinlateral nut pocket through the exterior wall of the tie in combinationwith a bolt which holds the flange of the rail, a nut in the pocketwhich receives the end of the bolt, the side of said nut bearing againstone wall of the pocket when the nut is in position, and a downwardlyextending opening of smaller area than and below the bottom of thepocket.

10. A concrete tie having avertical bolt hole and an intersecting thinlateral nut pocket through the exterior wall of the tie in combinationwith a bolt which holds the flange of the rail, a nut in the pocketwhich 1 receives the end of the bolt, said nut pocket of approximatelythe same cross section as the nut, the inner edge of the nut bearingagainst the inner surface of the pocket, and a downwardly extendingopening of smaller area than and below the bottom of the pocket.

11. it concrete tie having avertical bolt hole and an intersecting thinlateral nut pocket through the exterior wall of the tie of a size tosnugly receive the nut and center it below the bolt hole.
